Philly.com says the company CEO Michael Bennigan shared this news with industry analysts during a conference call about the company's quarterly earnings on Wednesday, saying the amount of interest in the plans to ship natural gas liquids across the Pennsylvania necessitates the second pipeline.

But Rolfe Blume, of Upper Frankford Township, said the right-of-way agreements some of his neighbors signed for the Mariner East II already called for the potential of that second pipeline.

"They're going to go through and disturb everyone's property, and then go through and disturb everyone's property a second time," Blume said on Thursday.

He and several other neighbors fought Sunoco Logistics in Cumberland County Court, where Judge M.L. Ebert in July ruled against their preliminary objections, leading to Blume filing an appeal with the Commonwealth Court.

A hearing is set for March 6.

Though Sunoco had all along planned two new pipelines as part of the Mariner East II project, according to Philly.com, it was the DEP's recent approval of water-crossing and sedimentation permits that made it official.

Work has already begun on the new 20-inch diameter pipeline, which the company says will be followed by a 16-inch diameter pipeline next to it to increase the amount of natural gas liquids that can be shipped, according to reports.

While work has begun, the part of the project that will be going through Blume's land is still in the hands of the court.

"I haven't agreed to anything," Blume said.

Through their attorney, Mike Faherty, Blume and his neighbors argued that Sunoco Pipeline does not have the authority to take a piece of their land.

Faherty told the court last year that under state law, eminent domain cannot be used for private enterprise, even if there is an element of public use, which he said is the situation here.

The pipeline will move liquid natural gas from Ohio through Pennsylvania to the Delaware River for shipment overseas, making it subject to federal regulations and not the state regulations that allow for eminent domain, he said.

But like Ebert, judges in Huntingdon and Washington counties, as well in another Cumberland County case with different property owners, sided with Sunoco Pipeline and ruled it is indeed a public utility with the power to exercise eminent domain.

Sunoco Logistics officials testified that pipelines are safer and cheaper than shipping by highway or railroad. It would take 500 trucks daily to ship the proposed pipeline's capacity of 275,000 barrels per day at a cost of 20 to 30 cents per barrel, compared to 7 cents per barrel via pipeline.

And though some of the liquid natural-gas could be shipped overseas, some of it will be used by Pennsylvania customers, pipeline officials say.
